I am currently a third-year Ph.D. candidate at Nanyang Technological University (NTU), supervised by Prof. Lihua Xie from NTU and co-supervised by Dr. Yau Wei-Yun from Agency for Science, Technology and Research (A*STAR), Singapore. Before that, I received both my M. Eng. degree (2022) and B. Eng. degree (2019) from Zhejiang University (ZJU), under the supervision of Prof. Ronghao Zheng.

My research primarily focuses on planning and optimization problems in multi-robot systems, including autonomous exploration, active SLAM, and planning under practical communication and temporal constraints. I am passionate about uncovering the mathematical foundations underlying practical challenges in autonomous robotic systems for real-world deployment, utilizing tools from optimization, graph theory, etc. I am also actively seeking the combination of robotics and learning-based foundation models. Feel free to reach out if you’re interested in my work!
